I think you want to make validation disable when you click on lookup button
then add this to validation button
CausesValidation="False"
Thanks and Regards

With VisualStudio.Net, i'm using an installer class with a custom action
on my setup project to ask the user a serial number. A "Textboxes"
dialog on the "user interface" provides the serial number string to an
overrided version of then install procedure, inside my installer class.
My problem is that the install sub is able to verify the serial number
entered, but then i can't stop/cancel the installation procedure.

Hello, i have created a new thread to do some heavy stuff, it takes about 1-2 minute to be done, when the thread ends i want it to notify and change something in the gui, i cant access the gui from another thread so i tried creating a new delgate and invoke it, still it didnt manage to show changes in the gui... any idea?
i tried something like this:
protected btn_click(object sender, EventArgs e)
{
Thread t = new Thread(new ThreadStart(HeavyStuff))
t.start();
}
delegate void CleanGui();
void HeavyStuff()
{
// heavy stuff here
CleanGui p = CleaningGuiHere;
p.invoke();
}
void CleaningGuiHere()
{
}
|

- Create a new class doing all your heavy work...
- Create a public function to 'start' the work...
- Let the class raise an event if the work is done..
In your app create an instance of the class and an event handler which handles your event.
Create a new thread calling the exposed (public) function and start the tread.
The event will be raised when the work is done.
Note you cannot do any GUI interface changes in the event handler because the event was called from a difrent thread. Create a delegate in your 'main app class' which can be called using Invoke() from the event handler...
Hrmm... confusing explanation ... hope you understand it

I have a textbox whose CssClass is normally set to "requiredfield'.
However I would like to remove this CssClass sometimes (the textbox is on a webcontrol) and just have the textbox formatted according to the skin file.
I tried PhoneNumberTextBox.CssClass = ""; but this doesnt work.
What is the correct way to do this ?
|
|
|
|

OK textbox is on which web control can you post and where are you writing
TextBox.CssClass = "" ;?
Thanks and Regards

Hey Guys, I posted this on another forum with no luck. I figured I'd give it a try here too. If you know a solution... please don't be shy!!

I've been tasked with creating a webservice. It is useful to pass some parameters as custom objects. These custom objects are defined in a seperate assembly I'll refer to as SS. Both the webservice and the application consuming the web service reference the assembly SS. My problem is that the application consuming the service is changing the type of parameters. The following may help explain...
Assembly SS defines a User object (SS.User)
Web Service references assembly SS
Web Method takes SS.User as a parameter
WebMethod(SS.User TheUser) {
...
}
Application references assembly SS, I want to pass SS.User as a parameter to the web service but when I consume the webservice the method signature looks like this...
Service.WebMethod(TheApplication.TheWebServiceName.User)
My first thought was to create a SS.User object within the application then cast to TheApplication.TheWebServiceName.User then pass it. However, I get a compliation error as that cast is not allowed.
Any thoughts?? Is this expected behavior for some reason I don't understand??
---------------
this next part is my reply to a post, so it's not quite in context but adds some depth.
---------------
Anyways, yes. That I know. The object definition exists on both webservice side and on the application side. Both the application and the webservice independantly reference the SS assembly. The object data should just be serialized and passed to the service, then the object can be recreated on the server. Am I right??
Why when I consume the webservice does the webmethod signature not look like...
WebMethod(SS.User) ??? It looks like WebMethod(ApplicationNamespace.WebServiceName.User). And I can't cast from SS.User to ApplicationNamespace.WebServiceName.User.
This is maddening, because I swear I've done this before with no issues. GAR!

anwyays, thanks in advance for any replies

The application that is consuming the webservice does not need to pass an object of type SS.User. The webservice itself defines a proxy class that gets returned (TheApplication.TheWebServiceName.User).
You should be able to return a class of this type, i think.

OK, I see what you are saying. Does this mean that what I want to do is not really possible in the way I want to do it?

Hi
How to extract text from already existing captcha image.I have some captcha images(jpg format) with me,from that images i have to read the letters one by one and convert them as a string.
|
|
|
|
|
Generally speaking the point of captcha images is that its hard to do this. I would have to ask what it is you need it for.
|
|
|
|
|
From my point of view not possible ........
Easily you can't get text from image
Might be there are third party tools available check for that option
Thanks and Regards

All server controls that you use when you are developing a web application are web controls.
Most web controls support data binding in one form or another. If you choose to use the controls this way depends on if it suits what you want to accomplish.

The Formview option allows you to edit a row in a table, add a new row in a table, and delete a row in a table. How do you set up a formview where only the edit and new functions are enable but a user cannot delete a record?

What is the point of using data sources such as SqlDataSource or ObjectDataSource?
Consider a simple example of a web page with a dropdown list used to filter the content of a pageable, sortable GridView. Each control needs a data source and that results in two calls to SQL Server. We are also told to keep the number of "round trips" to SQL Server to a minimum, for best performance. These scenarios are incompatible (although the difference in my example is trivial).
The only solution I have spotted is to make a single call to a compound SQL Server stored procedure and to put the results in a dataset (a repeater cannot be used for a pageable, sortable GridView) and bind each control to the appropriate table in the dataset. The disadvantage to this method is that I now have to code the GridView Sorting and PageIndexChanging events rather than just supplying attributes for that control.

The objectDataSource is a very tool. It allows you to bind collection of objects to a gridview instead of always using a dataset or a datatable, dataview. I wrote and article on the objectdatasource and the gridview. Take a look at it and let me know what you think?
http://www.codeproject.com/useritems/GridViewObjectDataSource.asp[^]
I am currently using something close to what I showed in this article in production now. The objects and the gridview it self are a lot more complex, but the basic function is the same.
